Setting pkg_gpgcheck=0 (aka gpgcheck=0) in the .repo lets you install unsigned packages. That's how mock etc operate, and keep working over this change.

Hi Panu,

I can now confirm that we are indeed hitting this issue. Afaik we did set gpgcheck=0, and I am now digging into the code to confirm this.

Here are some failed jobs to reference:
- Copr artifact: https://artifacts.dev.testing-farm.io/ d3f1db58-2964-42d0-be60-9c6023d6acd4/ (inside "Copr build(s) installation" -> "6-Install-pakcages.txt") - Koji artifact: https://artifacts.dev.testing-farm.io/ a33f815a-9021-42d0-8fa5-8afefcc8da44/

Also see the "4-Add-repository.txt" I do see `gpgcheck=0`.

Okay so here at least, the issue is that the package file that is failing the check is specified on the command line directly, so no repository configuration affects that.

Note that this package IS signed, it's just that the key is not imported:
- package python3-scikit-build-core-0.11.6-1.20260217085946639536.pr1219.48.g8dce8a6.fc45.noarch does not verify: Header OpenPGP V4 RSA/SHA256 signature, key ID e2b551f502810203: NOKEY

The test is downloading the copr repo definition which includes the key info as well:
gpgkey=https://download.copr.fedorainfracloud.org/results/packit/scikit-build-scikit-build-core-1219/pubkey.gpg

So ideally, you'd download any gpgkey= from the copr repo and import it, and then it'll just work.

The brute-force variant is of course to just disable signature checking for that bit.

One would expect --setopt=localpkg_gpgcheck=false to the command line bypass that, but that doesn't seem to work. Which would be a dnf bug.
I'll have a look.

Hmm, that goes for --no-gpgchecks as well. Which was intentional back in 2018 but not so much now.

To workaround, override the rpm policy in the test running environment, as per the change docs:

    # echo '%_pkgverify_level digest' > /etc/rpm/macros.verify

I don't know how all that is structured so hard to give guidance on it, but that needs to happen before any commands that attempt to install local package files with dnf.


Can we check on what is going on here? Are we misconfiguration this or is this an issue with the implementation?

I don't know what the story behind that "local" plugin is, but there seem to be various workaround suggested?
The issue with dnf local plugin is different, and I suspect that the change they have made there will impact the users. It seems to be an opt-in feature at least, but it is a bug in dnf implementation iiuc. We reported this in upstream https://github.com/rpm-software-management/ dnf5/issues/2580

Ok.
